“…In addition, Jiang et al [74] started from natural citric acid and designed and synthesized two novel biosourced diamines, OAC and OOD, as shown in Figure 8. Using these diamines and commercial dianhydrides for polymerization, they obtained a series of polyimides with special optical properties and good optical activity.…”

With the rapid development of information, energy, and materials industries in China, the demand for high-performance polymers is gradually increasing. Photosensitive polyimide (PSPI) has emerged as an ideal choice for high-performance optoelectronic materials due to its outstanding thermal stability, mechanical strength, and low dielectric constant. In particular, bio-based photosensitive polyimide prepared from bio-based chemicals, as a green polymer material, not only reflects the advantages of environmental protection and resource efficiency but also contributes to carbon neutrality. However, how to improve the photolithography efficiency while maintaining the thermodynamic performance and environmental friendliness and how to balance the pros and cons of low-molecular-weight matrixes are still challenges in the research. This review systematically summarizes the synthesis and performance characteristics of photosensitive polyimides, bio-based polyimide, and bio-based photosensitive polyimides and further explores the future application prospects of bio-based polyimides in the field of high-performance optoelectronic materials.

“…Polymers possessing fused polycyclic structures in the main chain repeating units are often utilized as functional materials based on their high rigidity . In particular, π-conjugated polymers with unsaturated ring systems have been actively investigated for optoelectronic applications, and various structural motifs have been reported to date, including both carbocycles and heterocycles. , On the other hand, polymers with saturated fused polycyclic repeating units in the main chain have been significantly less explored, presumably due to the lack of efficient synthetic methods, although those with saturated monocycles exemplified by cyclic olefin polymers have shown promising properties such as high chemical resistance, high transparency, and high thermal stability. − To expand the accessibility to polymers with various saturated fused polycycles, it is desirable to design and realize a new method of polymerization for such molecular frameworks.…”

Polymers possessing saturated fused polycycles in the main chain repeating unit have been underexplored despite their potential utility based on their expected properties such as high rigidity, chemical resistance, transparency, and thermal stability. In this regard, herein, we developed a radical stitching polymerization of styryl vinyl ketones for the synthesis of polyketones possessing saturated fused bicyclic repeating units. The polymerization proceeded smoothly with a high degree of stitching efficiency in a chain-growth manner under free radical conditions. This method was further extended to the alternating copolymerization of styryl vinyl ketones and 1-styryl-2-vinylbenzenes, representing the first alternating stitching copolymerization of two different monomers. The obtained polymers were found to show promising thermal properties and high transparency in the visible light region.

Polyimides (PIs) are widely used in circuit components, electrical insulators, and power systems in modern electronic devices and large electrical appliances. Electrical/mechanical damage of materials are important factors that threaten reliability and service lifetime. Dynamic (self‐healable, recyclable and degradable) PIs, a promising class of materials that successfully improve electrical/mechanical properties after damage, are anticipated to solve this issue. The viewpoints and perspectives on the status and future trends of dynamic PI based on a few existing documents are shared. The main damage forms of PI dielectric materials in the application process are first introduced, and initial strategies and schemes to solve these problems are proposed. Fundamentally, the bottleneck issues faced by the development of dynamic PIs are indicated, and the relationship between various damage forms and the universality of the method is evaluated. The potential mechanism of the dynamic PI to deal with electrical damage is highlighted and several feasible prospective schemes to address electrical damage are discussed. This study is concluded by presenting a short outlook and future improvements to systems, challenges, and solutions of dynamic PI in electrical insulation. The summary of theory and practice should encourage policy development favoring energy conservation and environmental protection and promoting sustainability.
